We purchased a PIXMA MX452 printer in 2013. It is now out of warranty. We purchased a new Mac Book Air computer last week and were surprised that the Mac could only print in black and white. No other settings. The Canon website shows that there are no drivers for the Catalina macOS installed on our new computer. What do we do? We are anxious to print in grayscale and color. Also to scan documents. Surprised that a 6 1/2 year old printer is no longer supported. Would drivers for another printer work?
